Add your answer and earn points. State the image of the point. When given a coordinate point or a figure on the xy-plane, the 90-degree clockwise rotation will switch the places of the x and y-coordinates: from (x, y) to (y, -x). They are different operations. Say any object (e.g. Plot the original coordinates on a graph. On the right, a parallelogram rotates around the red dot. If R (x, y) is a point that needs to be rotated about the origin, then coordinates of this point after the 90 rotation will be R'= (y, -x) When rotated through 90 about the origin in the clockwise direction, the new position of point P (2, 3) will become P' (3, -2) So, each point has to be rotated and new coordinates have to be found.
